Assistant Research Scientist:

Dr. Zan Peeters completed his PhD at Leiden Institute of Chemistry where he focused on the analysis of organic molecules, their stability in different space environments and their subsequent role in the origin of life. He designed and built several space simulation chambers that were used to acquire data on the effects of UV photo-processing, temperature conditions, atmospheric conditions and the presence/absence of oxidizing agents on organic matter. He was sponsored by the Dutch Space Agency, SRON to prepare the “Organic” experiment for the EXPOSE facility on the International Space Station for flight. During his Postdoc fellowships at NASA Goddard and Carnegie Institution in DC, he expanded his research field to study organic matter in ice matrices as well as carbon-rich inclusions in meteorites. He was a Support scientist for the NanoSIMS laboratory at Academia Sinica in Taipei for 4 years.

In the current position at ASU, apart from doing independent research, he is also in charge of the daily operations of the NanoSIMS lab at ASU.

Postdoctoral Researcher:

Dr. Ziliang Jin received his Ph.D. at the China University of Geosciences, Beijing. His PhD thesis project was to study the genesis of Skarn-type iron deposits, which supply the highest grade iron ores in China. He also worked as a guest scientist in the GeoForschung Zentrum (GFZ) SIMS lab in Potsdam, Germany. Since matrix-matched reference materials are critical for SIMS experiments, he worked on the Cameca IMS 1280HR instrument to develop and characterize reference materials, such as the synthetic glass, synthetic olivine, apatite and calcite.

His current research work at ASU will focus on the study of volatile elements in anhydrous minerals from the asteroid Itokawa and other chondritic samples using the NanoSIMS 50L.
